good thought. Causes vs. predisposed. I think he may have said "causes". But then with genes, genotypical does not always mean phenotypical.
Don't know anything about Rhett's. Do know that Fragile X, although it causes patients to be symptomatic for autistic behaviors is a separate genetic disorder in which the X chromosome replicates with abandon within the blastula stage. My friend's son is symptomatic for autism but is actually diagnosed fragile x. His geneticist stopped counting the x's after 20. I presume Turner's syndrome would be the same way - symptomatic for autism, genetically fragile x (klienfelter's is fragile x for males, turner's is fragile x for females)
Could there be a separate genetic link between rhett's, fragile x and autism? Good question. I wonder myself. But then researchers might have to say there was a possible link with down's and cerebral palsy and so many other genetic anamolies because 50% of the children I know with those genetic disorders are also symptomatic for autism.
I also often wonder if there is link between autism, alzheimer's and schizophrenia. (my children's birthmother is schizophrenic but not autistic.)
